RAILWAY DUMP CAR.

Application filed August 28, 1922. Serial No. 584,603.

T 0 all whomit may concern Be it known that we, ELLIS L, HALE and HARRY G. CoULsoN, citizens oi? the United States, residing at Vallace, in the county of Shoshone and State of Idaho, have invented certain new an d useful Improvements in Railway Dump Cars, of Whiz-l1 the following is a specification. I

Our invention relates to certain new and useful improvements in railway cars used for hauling ore, coal, rock. earth, or the like, and it is intended to facilitate the tipping of the car body when dumping its eontents, and the restoring '01"- -the body to its normal position; also to provide means to automatically open and close the car door.

The invention further has for its object to rovide a dump car with a body arranged to e tilted toward one side or end which is provided with-a hinged door; an object of the invention being to provide a toggle lever locking mechanism for opening, closing and locking the hinged door accordingly as the body is tilted more or less and also to provide a single operating lever for effecting the tilting of the body and the simultaneous operation of the door.

Again the invention has for its object to provide a dump car of the character stated of a simple, strong and inexpensive nature by the use of which it is quite possible for the operator to distribute track ballast as a car moves slowly along by holding the operating lever in such position that the body is partially tipped and the door opened slightly so that the material gradually spills out; the amount of track ballast thus deposited being regulated to a 'nicety by holding the dumping or operating lever in a position to give the desired amount.

The invention further resides in those novel features of construction, combination and arrangement of parts. all of which will be first fully described, then be specifically pointed out in. the appended claims, reference being bad to the accompanying drawings, in which:

Figure 1' is a perspective view of a dump car embodying the invention, the view being taken from the dump lever side at one end of the car.

Figuie 2 is a view similar to Figure 1 taken from the other side of the can i Figure is a perspective View similar to Figure 1 with the car body completely tipped and. the door completely opened.

Figure 4; is a perspective view similar to Figure 2 with the body tilted and door opened to about iour fitths or" the maximum distance.

Figure 5 is an end elevation showing the car in the normal position in full lines.

ligitire 6 is a detail end view illustrating be p isition of the door operating toggle ock levers in the open position in full lines.

Figure is an enlarged detail elevation of a portion of the dumpingior operating lever and the link connection with the car body.

Figure 8 is a detail perspective view of the pivot portion of the dumping lever.

Figure 9 is a detail. perspective view of the link used to connect the dumping lever with the car body.

Figure 10 is a detail perspective view of the pivot bracket carried by the car body, to which one element of the toggle levers connects.

Figure 11 is a. detail sectional view showing the toggle levers connected to the bracket element and the bracket element connected to the car body.

In the drawings in which like numerals of reference indicate likeparts in all of the figures. the frame 1 (which may be made of wood or metal) is carried upon suitable car wheels 2 andaxles 3 and constitutes a truck. Bolted to the frame 1 are three bodysupports 4. 4 and 5-, each of which is provided with an inclined portion 4-, 4i and 5", respectively, to act as a stop or rest for the car body in the fully tilted position. The car body 13 is pivotally attached to the supports (I-beams being shown in the embodiment of the invention illustrated) by means of angles 6. bolts 29 and pivot blocks 7.

Attached to the middle support 5 by bolts 9 is a dump lever pivot 8. Pivoted upon the dump lever pivot 8 is the offset bell crank portion 11 of the dumping leverlO. AnI- block 12 is attached to the body 18 and is connected to the lower arm of the bell crank 11 by means of a link 14. The lever is held in normal position by the keeper link 16 which is kept in place by the D-clip 1 5 riveted to the body. To tip the car body, the lever 10 is loosened from the link 16 and turned about its pivot 8 through an angle of about one hundred and thirty degrees until it strikes the stop piece 1?. The body is restored by bringing the lever 10 back up to the first position.

The door 18 is hinged by means of a rod 19 to he upper corner of the body 13 and )ivot post 21, upon which is .l pair of horizontal leuting one element of a toggle m), the inner end of the pair of I, l on constit which has its outer end pivoted to the trunnion 20. The frame 1 has mounted upon it, at each end, a link bracket 24:'

which is provided with a pivot pin 25. The pivot pin 25 is connected by upright link to a pin 2 in th 111 horir-aontal le 2 bent pass over ll. an! the upper end of t so that in the normal poter. The pin 27 acts as a fulcrum for the lever 22, and at the same time swings on a downward are about the pin 25 as a center. Because of the relative locations and travel of the pivot post 21 and fulcrum pin 27, the end of the lever 22 and the pin 28 describes an are about post 21 as a center. This movement of pin 28 is imparted to trunnion 20 by the link 23 and serves to swing the door 18 outward about the rod 19 as a center. The lever 22 and the links 26 and 23 act in the reverse order to close the door 18 when the body 13 is restored to its normal position by the action of the lever 10. When the body is nearing its normal positiomthe link 23 and lever 22 have apovferful toggle action which brings the door 18 tightly up against the body 13.

The chief advantage of the dumping lever is that cars of any size may be easily dumped by one man. It also makes possible the use of larger cars, which could not. before be dumped by the old direct hand method of tipping. The main advantage of the door opening; and closing mechanism is that it is entirely automatic; no additional hand leyers or latches of any kind are necessary and furthermore the door is more securely held thanby most other devices. An advantage secured by the coinj of dumping lever and automatic door mechanism is that operator is able to distribute track bala car moves slowly along by holding dumpin lever in such a position that body partially tipped and the door d slightly so that material gradually c1. ills out. The anioui'it of track ballast thus mositcd may be regulated to a ninety by the dumping lever in a position to give the desired amount.

t a or sheds 30 may be provided on the car body above the toggle lever mechanism to shunt any spilled rock or material a v y debris clog their scion.

While have illustrated our invention as a metallic dump can it is to be understood that the material employed in constructing the body and. truck may be any that is suitable for the purpose.

From the foregoing description, taken in connection with the aecompanying drawings, it is thought the complete construiion, operation and advantages of our invention will be readily understood by those skilled in the art to which it appertains.
